WILLIAM A. HENDERSON, VOF LARCHMONT, NEW YORK, ASSIGNOR TO HOLBROOK COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

CONCEALED HINGE.

Specification of Letters Patent.

Patented Jan. 21, 1.919.

To all wiz/0m, t may concern.'

Be it known that I, WILLIAM A. HENDnnsoN, a citizen of the United States, and resi* dent of Larchmont, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Concealed IIinges, of which the following is a specification.

This invention relates to hinges and more especially to that class known as concealed hinges and wherein the parts are so 1nclosed as to be better able to support a door or swinging member and be less liable to catch articles of clothing. The device 1s moreover strengthened by the location of its pintle and certain features are provided to prevent the cracking and marring of the paint on the frame and door of a coach or other structure. These and other objects and details of the invention are more fully described in the following specification, set forth in the claims and illustrated in the accompanying drawings, wherein:

Figure 1 1s a perspective view of the hinge detached.

Fig. 2 is a horizontal sectional View of the device with its door closed.

Fig. 3 is a similar view with the door open.

Fig. 4 is a vertical sectional view on the line 4 4 of Fig. 2.

When closed the hinge fits into and is concealed by a socket casing 5 inserted in a mortise in the woodwork or frame 6 of a coach or building, the casing having upper and lower ianges 7 by which it is secured to the frame by means of screws 8. This casing is broad and shallow to aiiord a substantial bearing for the housing 9 which carries the arm or hook 10 pivoted within the said housing by means of the pintle 11 and its whole weight is practically supported by the lower wall of the housing while the rear of the casing has a recess 12 to contain the inner end of the segmental part 13 of the arm. The upper and lower sides of the housing are united by a front face 14; and a stop 15 is attached to the cas-- ing to limit the outward movement of the arm as shown in Fig. 3, the former constituting a plate with a slot 16 through which the arm 13 plays and it also has perforations through which pass screws 17 to secure it to the flanges 7.

When this class of hinges is secured to the coach frame and the appropriate paint and varnish applied, the strain on and the wear of the hinge causes the paint to crack and chip olf so as to present an unsightly appearance, and to overcome this defect in hinges heretofore used, the plate 14 overlaps the casing 5 and its ianges on all sides and hides its connections with the woodwork.

To the outer end of the segmental part 13 is an integral. plate 18 with screw holes to permit its being secured to the door 19.

Where the arm 10-13 is constructed as shown the broad bearing surface provides a firm and substantial support for the swinging member and the rear extension 20 of the arm practically closes the slot 16 when the hinge is open and thus providing a perfect closure, preventing clothing being caught therein or dirt or water from accumulating therein.

The device therefore provides a substantial and compact hinge adapted'to secure a neat finish to the vehicle and the hinge itself may be removed with the door by simply loosening the screws 17, the socket casing 5 being adapted for permanent location but ractically sustaining the entire weight of) the door and hinge.

It is obvious that the device may be modilied or the parts otherwise arranged without departing from the essential features above described or from the scope of the appended claims.

What I claim as new is:

1. In a. concealed hinge, the combination with a mortised door frame, of a casing fitting in the mortise and having attaching flanges, a plate adapted to cover the anges and having a slot, a horizontal housing secured to the plate and within the slot, an arm pivoted at its inner end to the housing and supported by the latter, and an attaching plate at the outer end of the arm.

2. In a concealed hinge, the combination with a mortised door frame, of a casing lling the inortise and having attaching the outer end of the erm to secure it to a flanges, a housing itted Within the casing door. Aand having an outer slotted plate to cover Signed at New York, in the county of 10 the casing and its flanges, an arm pivoted New York, and State of New York,` this 2d 5 at the rear of the housing and supported cla-y of July, A. D. 1917.

by the latter and adapted to swing through the slot of the covering plate and means at WILLIAM A. HENDERSON.

Copies of this patent may be obtained for ve cents each, by addressing the Commissioner oi Patents, Washington, E. 6.
